Transformation of NIH-3T3 cells by L858R or G719S EGFR was further assessed in two independent assays. Expression of the EGFR point mutants in NIH-3T3 cells caused loss of contact inhibition, resulting in focus formation
[Paragraph-level] PMCID: PMC1240052 Section: RESULTS PassageIndex: 4
Evidence Type(s): Oncogenic, Functional
Justification: Oncogenic: The passage describes how the L858R and G719S EGFR variants contribute to tumor development, as evidenced by their ability to transform NIH-3T3 cells and form tumors in immunocompromised mice. Functional: The passage indicates that the expression of the EGFR point mutants (L858R and G719S) in NIH-3T3 cells caused loss of contact inhibition, suggesting that these variants alter the molecular function of the EGFR protein.
